Introduction The world's largest hydroelectric power plant under construction on November 5, 2022. The 15th one million kilowatt hydroelectric unit was commissioned on November 5, 2022.

On November 5, 2022, the world's largest hydropower plant under construction, the 15th million-

On November 5, 2022, the 15th million-kilowatt hydropower generation unit of Baihetan Hydropower Station, the world's largest hydropower plant under construction, was put into operation to produce electricity.

A hydroelectric power station is made up of a hydraulic system, a mechanical system and an electrical energy production device. This is a water conservation project that converts water energy into electrical energy. production requires the uninterrupted use of water energy in hydroelectric plants. Through the construction of hydropower plant reservoir systems, the distribution of water resources in time and space is artificially adjusted and changed to achieve sustainable use of water resources.

In order to efficiently convert the energy of the water in the reservoir into electrical energy, the power plantHydroelectric power must be achieved through an electromechanical water system, mainly consisting of pressure bypass pipes, hydraulic turbines, generators and tailrace channel. pipes. The electromechanical water system realizes the conversion of water energy into mechanical energy through the cooperation of pressurized water pipes and hydraulic turbines.

Through the connecting relationship between the hydraulic turbine and the generator, the goal of using water energy for electric power generation is finally achieved. The amount of energy from the water in the tank that is converted into electrical energy is closely related to the force exerted at the nozzle of the pressure diversion pipe. Therefore, the factors that affect the force at the water diversion pipe nozzle, such as the tank. water volume, tank water level and inclination angle of the pressure diversion pipe affect ddirectly the efficient conversion of water energy into electrical energy.

Thus, the process of producing electrical energy in a hydroelectric power plant consists of coordinating the operation between the reservoir and the electromechanical water system and between the different parts of the electromechanical water system. The hydroelectric power station system is essentially. an electromechanical coupling system to water.
